[Elecraft] OT; A question

[Richard Fjeld]

Decades ago, I remember seeing advertisements about a steel I-beam type rail  that bolted vertically to the side of a utility pole.  There was a trolley type device that was winched up and down the beam by a pulley at the top of the beam.  The trolley had provisions for mounting a rotor, or other stuff.

I would like to know more about that unit, and if they are still sold.  If you have information, or have seen one, please tell me about it.

Thanks,
